Title: A Method and an Apparatus for Precipitation Coating of Internal Surfaces in Tanks and Pipe Systems
Inventor: AANESTAD LEIF I
IPC: C23C18/16
Filed: 1993-05-10
Abstract: A method and an apparatus for coating tanks and pipe systems internally in that, first, a tank (1) is filled with a liquid (3) consisting of water to which is admixed an acid (10). Oxide coating on the internal surface is removed through heating and circulating the liquid (3) through a filter (4). The liquid (3) is neutralized through the admixture of a base (12). Approximately one fifth of the neutralized liquid (3) is drawn off, the tank (1) being refilled with a concentrated metal solution (15). The temperature, acidity and metal concentration of the liquid (3) are maintained close to constant through supplying heat, acid (10) or base (12), and concentrated metal solution (15), respectively. Air or vapour is supplied through a blowing pipe (5) and creates stirring, surplus liquid and gas being drained through a pipe (16). When the internal surface of the tank (1) has received a coaling having the desired thickness, the process is interrupted in that the liquid (3) is cooled and drained.

Title: Method of and apparatus for bending glass sheets
Inventor: WOODWARD ALAN CHARLES
IPC: C03B23/03
Filed: 1995-04-12
Abstract: METHOD OF AND APPARATUS FOR BENDING GLASS SHEETS                   ABSTRACT OF THE DISCLOSURE   The glass sheet is heated to a heat-softened condition in a furnace, and conveyed to a prescribed position above an upper shaping surface of a ring mould. The sheet is then transferred onto the ring mould by lowering part of the conveyor means, and bent by a process involving raising both the ring mould and the conveyor means. This combination minimizes the introduction of optical distortion into the sheet. A preferred bending process is to press bend the sheet between the ring mould and an opposed upper bending mould.

Title: Improved photokeratoscope apparatus and method
Inventor: VAN SAARLOOS PAUL PHILLIP
IPC: A61B3/10
Filed: 1994-09-21
Abstract: An improved photokeratoscopic method and apparatus for measuring corneal curvature and topography. The principle of parallax is used by generating a reference light point (LP) outside of the relevant plane of a ring generator (3), such that the relative apparent position of the reference light point (LP) with respect to the projected light rings provides a calibration reference that varies with distance of a cornea from the photokeratoscope.  More particularly, the invention determines the coordinates in space and the tangent angle of the reflection point on the corneal surface of the image of the reference light point (LP). This information defines the actual corneal topography at the reflection point, without making assumptions. These coordinates and tangent angle can be used to determine the actual distance (d) from the photokeratoscope lens to the apex of the cornea. An exact value of (d) permits better accuracy in calculating the central corneal radius of curvature and corneal topography. The present invention can be used with any known photokeratoscope geometry, including planar, sphericl, or conical ring generators. The algorithm for computing (d), and for calculating the central corneal radius of curvature and corneal topography, is shown in pseudocode, and may easily be implemented as a computer program.

Title: Air-powered apparatus for filling grain drills
Inventor: SMITH DAVID R
IPC: A01C15/00
Filed: 1996-02-27
Abstract: An apparatus for filling a grain drill with grain includes a grain hopper and a manifold assembly.  The hopper includes an open upper portion and a lower portion, and a conveying conduit communicates with an outlet in the lower portion of the hopper such that grain exits the outlet into the conduit.  An air blower device is positioned at an end of the conveying conduit and forces pressurized air through the conduit and beneath the hopper outlet.  The air in the conveying conduit entrains grain exiting ?e outlet and carries the grain along the conduit to the manifold assembly mounted on the planting apparatus. The grain and air pass into a manifold tube having a delivery slot and air exhaust apertures, with the grain passing through the slot into the grain drill and the air exiting through the exhaust apertures. The hopper, blower device and conduit may be formed as a stand alone unit which, during filling, is connected to the manifold assembly that is secured to the grain drill.  In addition, the hopper and blower device may be formed as a unit that is mounted on the frame of the grain drill so as to be movable between a storage or transport position and a filling position.

Filed: 1995-01-02
Abstract: A device   (1)  is described for introducing a foil strip (7)  coming from a stock roll (5) into the pinch (2) between two rollers (3, 4), for instance simultaneously  with  a  plate (8) or other flat object onto which  the  foil  must  be arranged by means of an adhesive layer.  The device (1) is characterized  by braking means (9, 10, 11, 12, 20) placed between the stock roll (5) and a roller (3) to exert a braking force on the foil strip (7). The device can for instance be   embodied   such  that the  braking  means (9, 10, 11, 12, 20)   comprise  a fixedly disposed braking surface (10)  or a braking cylinder (20). A particular embodiment has the feature that a free-rotating guide roller (22, 24) is arranged between the stock roll (5) and the braking cylinder (20) which guide roller (22, 24) determines the tangent plane along which the foil strip (7) reaches the braking cylinder (20).  Since the tangent plane (21) along which the foil strip (7) leaves the braking cylinder (20) is stationary, the free-rotating guide roller (22, 24) determines the angle (.alpha.) at which the foil strip (7) lies against the braking cylinder (20).

Title: Self-illuminating touch activated optical switch
Inventor: SCHMUTZ LAWRENCE E
IPC: G02B6/35

Abstract: The present invention teaches a touch activated switch. The switch comprises a light source for generating a light ray. Further, the switch comprises a first lens for collimating the fight source's light ray. The first lens, as a result, generates a collimated light ray in a first direction. In a second direction, the first lens forms a first and a second focal point, such that the fight source is positioned at the first focal point. Moreover, the switch comprises a second lens for converging the collimated light ray to a surface. This surface scatters the collimated light ray in the direction of fire first lens when the surface is substantially touched. The switch also comprises a detector for detecting the collimated fight ray which has been scattered by touching the surface, with the detector being positioned at the second focal point, such that the switch is activated in response to touching the surface.
